TlRE FOR CYCLE OR OTHER WHEELS.

SPECIFICATION forming part of Letters Patent No. 516,313, dated March 13, 1894.

Application filed December 21, 1893- Serial No. 4941 (N0 modem To all whom it may concern.-

Be it known that we, ALoirsIUs JosEPHUs JOHANNES LINDNER and MAURICE ADLER, sub ects of the Queen of the Netherlands, and residents of Amsterdam, in the Kingdom of the Netherlands, have invented a certain new and useful Improvement in Tires and Rims for Cycles or other Vehicles, of which the following is a specification.

This invention relates to tires for cycles and other vehicles and consists in the improvements, constituting the tire hereinafter descrlbed, to which we have given the name arrektorf Reference being made to the annexed drawings, Figure 1 is a side elevation of the tire, or a portion thereof, with exterior envelope removed showing the tire attached to the mm. Fig. 2 is a longitudinal section on line 2, 2, Fig. 3. Fig. 3 is a cross section through the tlre, rim, and envelope on line 3, 3, Figs. 1 and 2. Fig. 4. is a side elevation of the tire, when under compression, the exterior envelope being removed.

The tire consists of three parts or layers, an lnner layer of cork, as a preferable material, B, having its outer surface serrated or corrugated so as to form alternately raised r dges b and hollows b; a middle layer 0 conslstingof a fiat band of guttapercha or equiva lent rubber composition; and an outer layer A, preferably of cork having its inner surface serrated or corrugated so as to form alternate ridges a and hollows it. These three parts are assembled as shown in Fig. 1 so that the ridges a are above the hollows b and the rldges h under the hollows a. The inner layer B is secured to the rim and by preference we use a hollow rim D with a Hat bed surface for the tire and turned up edges bent inward at d to secure the tire to the rim. The faces of the ridges 0t and b are connected to the band 0, by cement.

This tire, we inclose in an envelope E which may be of usual construction being made thicker at the sole e and attached on the-rim for instance at e by cement, or any of the known methods of fastening such envelopes.

When this tire is compressed by contact with the ground the layers A and B are pressed together and with the band C assume the position shown in Fig. 4. When the pressure ceases the parts return to their original posithickness of the band C, by varying the tension of this band which may be put on loosely or under tension, by altering the pitch or distance from center to center of the teeth and making them broader or finer, or lastly by making the teeth higher or lower.

Having now particularly described and ascertained the nature of this said invention and in what manner the same is to be performed, we declare that what we claim is- 1. In a tire for cycles or other vehicles the combination of an inner layer B serrated on its outer surface, a resilient middle layer 0 and an outer layer A serrated on its inner surface, the serrations of the layer A being alternated with regard to those ofthe layer B substantially as and for the purpose set forth.

2. In a tire for cycles or other vehicles, the combination of an inner layer B serrated on its outer surface, a resilient middle layer 0 cemented to the summits of the said serrations and an outer layerA serrated on its inner surface and having the said serrations cemented to the middle layer 0 in positions intermediate between the serrations of the layer B substantially as and for the purpose set forth.

3. In a tire for cycles or other vehicles the combination of a layer B transversely serrated on its outer face, an intermediate resilient and in normal position. flat layer 0 and an outer layer A transversely serrated on its inner face, the latter serrations being alternated with the former substantially as and for the purpose set forth.

4. In a tire for cycles or other vehicles the combination of an inner layer B having on its outer face transverse ridges b and transverse recesses 12 between said ridges, the latter being wider at the mouth than the outer faces of the ridges; an intermediate resilient band C in-contact with the outer faces of the ridges; and an outer layerA having on its inner face transverse ridges a and transverse recesses a between said ridges, the faces of the ridges a edges 01; With a tire composed of serrated inbeing in contact with the outer face of band ner layer B, resilient middle layer 0 and ser- C at surfaces opposite the recesses 11, substanrated outer layer Aarranged substantially as I 5 tially as and for the purpose set forth. set forth; and an exterior envelope E, the 5 5.
